Patented Dec. 3, 1940 OFFICE COMBINATIONDUMBBELL AND INDIAN CLUB NathanL. Paves, ew York; N. Y. Application yAplilv27, 1939, Serial N 270,271 4claims. (c1. 272-84) This invention relates to implements used inperforming physical exercises, particularly in developing the muscles ofthe-arms,.back and hands to a high degree of efliciency.

- `In gymnasia the more common appliances are Indian clubs anddumbbells, Awhich the habitues are taught to handle scientically andytrained in many maneuvers, tending to promote good health, increasestrength, inculcate gracefulness in action, and generally acquire poisein movement of a highlyv desirablenature. In the home, where room isrestricted, the paraphernalia is necessarily limited in scope, and theexpense usually is also considered.

Having these matters in mind,` and fully rec-` ognizing the valuableeiect of even moderate exercise, it is an object of this inventionto-provide a simple appliance combining the characteristics of a cluband dumbbell, so arranged that it can be metamorphosed into conditionAfor use in either form.

A further feature is `in the provision of anV appliancesuited forservice by persons ofeither sex and varying in age and physique, whoseekl to secure the advantages derivedA by proper eX- possiblyconstrained to home' ercise, although practice; A l y l Another purposeis to produce an implement of inexpensive constructie admirableappearance, and capable of being changed to operate either as an Indianclub or dumbbell, easily, quickly, and without the use of tools orextraneous means.

These meritorious aims are accomplished by the novel construction andarrangement of few and simple parts, hereinafter described andillustrated in the accompanying drawing, constituting an important partof this disclosure, and in which:

Figure 1 is a front elevational view of an embodiment of the inventionassembled to represent a conventional Indian club. l

Figure 2 is a central longitudinal sectional view of the same.

Figure 3 is a sectional detail view of a removable shank handle having arod Wrench enclosedtherein. y

Figure 4 is a View of an insertible bar by which the weight of thedevice may be increased.

Figure 5 is a fragmentary sectional view showing a method of locking theshank handle to the body of the device.

Figure 6 is a plan view of the locking member.

Figure 7 is a fragmentary sectional view showing a modied form ofsecuring the central tube in the club head before being locked therein.

Figure 8 is4 a view similar to Figure '7, showing the tube securelylocked to the head.

.Reference to the drawing will show a main body,.,gener`ally designatedAby the numeral I5, of circular'cross sectionl throughout, ashaving 5 ahead I 6, preferably concave at its extremity I1 and `of ellipticalconfiguration.

An annular recess I8, in its largest diametered portion I6, has set init a cushion ring I9,as rubber, to dull the .sound of striking objects,10 and for the further purpose of avoiding injury to them.

A swelled handle nected by a reduced portion 25, integrally conneck 2|to the head, is similarly reduced, as at. the neck 22, and blending intoan enlarged end 23, soshaped and proportioned as to substantially 4equalthe weight of the head I6, when the handleV is grasped.

.'I'hese unitary elements contain an axial` bore 24 in Which is secureda tubular sleeve 25, its 20 inner end 26 corrugated or threaded tobecome permanently fixed in the head I6, these Velements constituting,in effect, a dumbbell.

When desired to use' the device as an Indian club,` an auxiliary handle3U is joined to the 25 element `23 as a continuation thereof, the handle30 having a spherical knob 3l at its outer end.

lFixed in the knob, prior to its being rigidly fastened on the handleend 30, is a bushing 32, interiorly threaded to receive the correspond-30 ing end of a rod or clamp bolt 34, having an enlargement or head atits opposite, inner end and provided with screw threads 36 to engageWithin the threads 21 of the sleeve 25, thereby to iirmly unite thehandle 30 to the ele- 35 ments of the dumbbell, the effect being toproduce a form of Indian club.

If more weight is desired, a bar 40 of metal, as lead, iron, etc., maybe inserted into the sleeve 25 and held by its screw fitted to engagethe threads 2'I In order to insert and lock outer terminal 42 isiiattened by a fork 43 formed in the enlarged end 35 of the combinationbolt and wrench 34. Ob- 45 viously the bar 40 may be retracted byreverse manipulation of the element 34.

To avoid unintentional relative rotation of the handle 30 and body I5, arecess 45 is formed in the element 23 and pivoted in the recess, as by a50 pin 46, is a detent lever 41, its longer arm 48 engageable in agroove 49 in the handle 34, and is normally held therein by virtue-of aspring 50.

One end of the spring 50 is set in an indentation 52 in the bottom ofthe recessL 45, to im- 55 in the sleeve.

the bar 4), its and engageable threads 4|, which are 40 l the .opening21%. .After pingeagainst the broadened, opposite end 5I of the detentlever, a boss 53 being provided on the lever to retain the spring inoperative position. Obviously, when the end of the lever, at at 5l, ispressed inwardly, it releases the arm 48, permitting relative rotarymotion of the handle and body as indicated in dash dot lines in Figure5;

Referring to Figures '7 and 8 showing a modied formv of securing thesleeve 25 within the bore 2li. Itis obviously very essential to retainthe sleeve 25 securely vwithin the upper portion of the club l5 'toprevent the accidental disengagement of the club from' the handle 34attached to the tube 25 while 'the clubl is b'i'iig swung'or otherwisebeing used for exercising. rIhis is accomplished by forming a pluralityof` tongues in the end 6| of the sleeve 25. These tongues f arepreferably forn'idlwith hook-lile`" elements $2 and are pressedinwardly, as shown in Figure 7 when the sleeve 25 is inserted it' thesleeve has been l'ocated in its properv place within the opening l2li,

a.,plungerxtype-too1 63 is inserted in the sleeve 25, and forced againstthe inwardly bent tongue Bil, thereby spreading the tongues and forcingtheirhook-like elements 62 into the wall ofthe bore 24, in the head l,thus securely locking the .sleeve 25 within the vclub member l5. Y

It is to beunderstood that` all kparts are suit-r ablyV nished and when.assembled present smooth surfaces, the vdetent lever elements beingflush and level with the surfaces in whichthey are set. i l

From the foregoing it will be seen that an effec*- tive',l doublepurpose,A exercising appliance has been disclosed inthe preferred formof itsY embodiment, but it is to be understood that changes may be madein form, proportions and in such 'minor details as maycome within thescope of Having 'thus described the invention,
